OpenAI reports the logarithmic Brunn–Minkowski inequality

For all origin-symmetric convex bodies K and L in every dimension and every interpolation parameter t in [0,1], the volume of their logarithmic Wulff combination is at least |K|^(1−t)|L|^t.

What was already known

Earlier results covered the planar case and coordinatewise unconditional bodies. The manuscript also notes Stancu’s all-dimensional announcement, with key flow-asymptotic details deferred; this provides a complete formalized argument for the selected statement.

AI involvement AI-led

OpenAI credits itself as manuscript author and states that its internal frontier model produced the results in this release. Individual human input is not detailed enough to establish task-only autonomy.

OpenAI is named as author on the manuscript, and its release attributes the results to an internal frontier model. The individual human input is not detailed enough to establish autonomy.

Importance Major

Resolves the all-dimensional logarithmic Brunn–Minkowski conjecture for origin-symmetric convex bodies.

Limitations

The selected claim concerns Lebesgue volume of origin-symmetric bodies. The paper’s Lp, log-concave-measure, and B-conjecture consequences are outside the pinned Lean scope.

Technical verification Formal (Lean 4)

OpenAI reports a Lean proof matching the selected claim.

Formal checking

The pinned Lean note gives the sharp logarithmic Wulff-volume inequality for all origin-symmetric convex bodies in every dimension.

Evidence source

Checking a formal statement does not establish that it matches the original problem.

Human understanding Few

Few is the default when evidence for a higher level is insufficient. No named person is documented as explaining the central argument for this assessed contribution.
